The development of atherosclerosis is strongly associated with an increased risk for cerebrovascular accidents (CVA), including stroke and transient ischemic attacks (TIA). Certain unique occupational exposures that individuals in the NASA astronaut corps face, specifically high-performance aircraft training, SCUBA training, and spaceflight, are hypothesized to cause changes to the cardiovascular system. These changes, which include (but are not limited to) oxidative damage as a result of radiation exposure and circadian rhythm disturbance, increased arterial stiffness, and increased carotid-intima-media thickness (CIMT), may contribute to the development of atherosclerosis and subsequent CVA. The purpose of this study was to review cases of CVA in the NASA astronaut corps and describe the comorbidities and occupational exposures associated with CVA.
